Fixed "Cannot read properties of undefined (reading 'arrayToDataTable')" error caused by calling Google Charts API before it finished loading. Changes: - Move google.load() call below function definitions - Use callback parameter to ensure charts load after library is ready - Add guard check in drawChart2() to verify google.visualization exists - Wrap chart drawing in $(document).ready() within the callback This ensures the visualization library is fully loaded before attempting to create charts, preventing race condition errors. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
